A bar magnet is brought near a solenoid ...

A bar magnet is brought near a solenoid as shown in figure. Will the solenoid attract or repel the magnet?

Text Solution

Verified by Experts

When the magnet is brought near the solenoid, then according to Lenz's law, both repel each other. On the other hand, if the magnet is moved away from the solenoid, then it attracts the magnet. When the magnet is brought near the solenoid, then the nearer side becomes the same pole and when it is moved away it becomes the opposite pole as shown in figure.

It can also be understood by increasing or decreasing field lines as in Example.
